Коротке пояснення:

Посередник (Mediator, Intermediary, Controller) — це поведінковий патерн проектування, що дає змогу зменшити зв’язаність великої кількості класів між собою, завдяки переміщенню цих зв’язків до одного класу-посередника.

CoR-pattern

Коротке пояснення:

Ланцюжок обов’язків (CoR, Chain of Command, Chain of Responsibility) — це поведінковий патерн проектування, що дає змогу передавати запити послідовно ланцюжком обробників. Кожен наступний обробник вирішує, чи може він обробити запит сам і чи варто передавати запит далі ланцюжком.

How to Run a Rails App in Production Locally
  1. Add gem 'rails_12factor' to your Gemfile. This will add error logging and the ability for your app to serve static assets.
  2. bundle
  3. Run RAILS_ENV=production rake db:create db:migrate db:seed
  4. Run rake secret and copy the output
  5. From the command line: export SECRET_KEY_BASE=output-of-rake-secret
  6. To precompile your assets, run rake assets:precompile. This will create a folder public/assets that contains all of your assets.
  7. Run RAILS_ENV=production rails s and you should see your app.

Remember to clobber your assets (rake assets:clobber) and re-precompile (rake assets:precompile) if you make changes.
